Add MOTD display to hgweb and hgwebdir.

The hgweb "footer" template now has space for an optional message of
the day (MOTD). This is used in two contexts:

1) On the hgwebdir index page
2) On various pages of each individual repo

For both cases, the MOTD is read out of an entry named "motd" in the
[web] section of a config file -- the only difference is which file is
used. For #1, you need to add the section to hgweb.config; for #2, you
need to add to the repo's .hgrc file.

I suggest something like this:

[web]
motd = <p>To download these repositories, <a href="http://www.selenic.com/mercurial">get Mercurial</a> and then type something like:</p><p><pre>hg clone http://gs3080.sp.cs.cmu.edu/hg.cgi/cpmpy</pre></p>You can also click the Download links to get an archive of the latest revision.
